This is what the 2.5 RS JDM manifold looks like with all the junk attached to it

After clearing off all the bolt on pieces you end up with something that looks like the following

After two and a half hours of cutting and grinding you end up with something that looks like the pictures below. You can see where I started grinding off the lower runs that end up going to a tube that sticks up right in the center of where the inlet is.

After another two and a half hours the following night I ended up getting it all finished. There are a couple holes that will be patched/welded and then ground down smooth. Once all the test fitting is done it will go out to the polisher

I left the two threaded tabs on the bottom because they line up with where the throttle body cable will need to run. I figure these will make good mounting points for a bracket holding the cable on the bottom of the manifold.

So it looks like my DBC Throttle body isn't going to fit/work without a bit more fabrication on the 2.5 RS intake manifold. For one the bolt pattern doesn't match up, and they aren't the same size bolts either.

Plus if you look at the back of the WRX throttle body you'll see that there is a little channel that matches up with the intake manifold to let air up into the top sensor. Of course this isn't there on the RS manifold.

First I posted in Cribbie's thread to see if he had an adapter plate, because it looks like he ran into the same scenario. Then I realized I could just cut the mounting area off of a junk stock WRX intake manifold and weld it onto this new 2.5 RS one.

Looking to pick up a spare WRX intake manifold tomorrow and do the cutting tomorrow night.
